Abstract

TITRE : DISPOSITIF DE DETECTION DE PRESENCE DE POLLENS DANS L’AIR, ET PROCEDE DE DETECTION CORRESPONDANT La présente invention concerne un dispositif de détection de présence de pollens dans l’air (1), comprenant une chambre de mesure isolée de la lumière extérieure, des moyens d’entraînement d’un flux d’air à travers la chambre de mesure, et une source lumineuse émettant un faisceau lumineux dans une direction de propagation passant par le flux d’air, dans la chambre de mesure. Selon l’invention, le dispositif (1) comprend au moins quatre capteurs photosensibles aptes à mesurer le flux lumineux diffusé par le flux d’air éclairé, dans quatre directions différentes, une horloge (37), au moins deux capteurs météorologiques, et au moins un calculateur (5) apte à déterminer la nature d’une particule de pollen présente dans l’air à partir des données mesurées par les capteurs photosensibles, l’horloge (37) et les capteurs météorologiques.
